Cut a slice from the stem end of each pepper to create a cap, then scoop out the seeds and rinse the interior.
Plunge the prepared peppers into a pot of boiling water for 3. 0 to 4. 0 minutes to soften slightly.
Remove the peppers from the water and drain them thoroughly by placing them cut-side down on a towel.
Add 1. 0 tbsp (6g / 0.21 oz) cumin, 0. 5 tsp (1g / 0.04 oz) turmeric, 1. 0 tsp (2g / 0.07 oz) chat masala, 0. 25 tsp (0. 5g / 0.18 oz) cayenne, 0. 5 tsp (2g / 0.07 oz) sugar, 1. 0 tsp (6g / 0.21 oz) salt, and 3. 0 tbsp (8g / 0.28 oz) fresh coriander to the potato mixture.
Sprinkle 2. 0 tbsp (14g / 0.49 oz) of roasted chickpea flour over the mixture and stir well until the stuffing is combined and dry.
If using cheese, place approximately 0. 5 tbsp (7ml) of cheddar into the bottom of each pepper and shake it toward the tip.
Carefully spoon the potato stuffing into the peppers, packing it lightly to avoid tearing the skins, and then replace the pepper caps.
Arrange the peppers in a single layer in a baking dish, ensuring they are barely touching.
Melt the remaining 2. 0 tbsp (1. 0 oz / 28g) of ghee or butter, brush the dish and the peppers generously, and bake at 350°F (180°C) for 30. 0 to 40. 0 minutes until fork-tender and browned.
